I know my first reaction to this news was that Star Wars: The Old Republic is toast.

Unlikely, at least in the short term. EA will certainly have signed a multi-year licensing deal with LA/LF, which I would expect to still be legally binding under the Disney buyout. I think it is far more likely for EA to pull the pin than Disney.

Far more troubling is the focus on mobile/social games. Seems like there's even less chance now for a revival of the classics like the X-Wing and Dark Forces/Jedi Knight series.
